Veins of the vertebral column

This tutorial covers the anatomy of the vertebral column, focusing on its venous drainage system. It explains the structure of vertebrae and the role of venous plexuses, including internal and external plexuses, in draining the vertebral column. The tutorial also discusses the clinical significance of these veins, particularly their lack of valves, which can lead to distension. Key veins such as the ascending lumbar veins and Basie vertebral veins are highlighted, along with their connections and functions.

How do the ascending lumbar veins relate to the azygous and hemiazygos veins?

What is the significance of the vertebral veins having no valves?

What clinical conditions can increase the risk of trauma during procedures involving the vertebral veins?
